The Sareer Willow Mattress is designed to give you the kind of restful, supported sleep you deserve-while also being kind to the environment. It's filled with a clever mix of three advanced polyester fibres, including a high-performance elastic fibre that helps the mattress hold its shape and bounce back night after night. The spiral-shaped fibres combine coarse and fine textures to give you the perfect balance of comfort, support, and gentle recovery. And thanks to its smart design, the Willow helps align your spine and prevents that annoying roll-together feeling-so you and your partner can sleep soundly. It also features a responsive Reflex layer that moulds to your body, easing pressure points and giving you that soft, supported feel without sinking in too much. Plus, it's breathable and great at reducing heat, helping the mattress stay fresh and cool through the night. Made with materials that are naturally flame-retardant (no added FR chemicals here!) and 100% recyclable at the end of its life, the Willow is as sustainable as it is supportive.
